They contain fewer non-perturbative corrections, at least to the leading order. Here we write such a sum rule for the correlation function of vector and tensor 'currents'. The odd and even chirality sum rules are taken together to evaluate the effective parameters of the $ρ$ meson to second order in temperature. To within errors, the results are consistent and reproduce the absence of shift in the $ρ$ meson mass to this order.7 pages, LaTeX, changed content, figure removedHigh Energy Physics - Phenomenologytext
